FLOOR-CLEANING MACHINE;

To allzu/wm #mag/.concern Beit'known that lI, Fnoon Sznwczux, a subject of theEmperorof Austria, residing at Fliiitfc'ountyof` Genesee, and State of Michigan,haveinvented certain new and useful :Improvements in Floor-Cleaning Machines,"of which the following is -a specification.

devices forcleaningffloors,and has as its special objectV lthei provision of .an apparatus which may be rolled over the surface to b e swept,the apparatus" containing a rotary" brush adapted for manual operation'whereby thedirt and accumulations 'are gathered and *delivered into` whence they maybe readilyremoved.'

A further 'object whereby the brush may be raised or lowered relatively to the surface over which the ap- `paratusmoves,v thereby providing for wear Vand also permitting it to be applied 1n a manner'fnot possibleto attain in `devices in which the brush is rotatably mounted in fixed bearings.

These. and other like objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a material part of this disclosure, and in which Figure 1 is a front elevational view, showing a scrubbing machine made in accordance with the invention.

Fig. 2 is a side elevational view of the same.

Fig. 3 is a vertical sectional view, taken on line 3*?) of Fig. 1, and

Fig. 4 is a fragmentary vertical sectional view taken on line 4-4 of Fig. 2.

The device comprises curved casing 10, with which are engaged end plates 11, the casing being mounted upon pairs of rollers 12, fixed to spindles 14, engaged in the end plates 11, the rear spin' dle 14 passing through a compartment 15, the outer wall 16 of which is integral with the casing 10, While the inner wall 17 acts as a partition, which in conjunction with the upwardly turned bottom plate 18, forms a compartment for the accumulations, as they are swept over the apron plate 19 by the brush.

Arranged over the plate 17 are a pair of hinges 20 by which is engaged a lid or cover i Specification of `Letters Patent.

' 21, provided with ar knob 22, having attached at its inner end alatch or button 23, cn-

gageable with the adjacent edge of the cas-` ing 10, the arrangement being such that the cover 21 may be heldin engagement with the casing.

Secured centrally to the end plates 11 are a pair of columns 25, having between them Thisinvention relates to improvements 1n a Connecting cross-bar'26, and a top bar 27 `so that the Acolumns are firmly secured to- `in the column 1s a` gether, and journaled collars 31 upon each shaft being formed into provided with operating hanend, the extending Mounted Von the shaft 30 is a bevel gear 35, in engagement witha bevel pinion 36,afixcd upon the endlof a vertical shaft 38, journaled in a bracketSQ, and also in the crossbar 26; @This shaft is preferably tubular and adapted to receive the reduced end `4() of another shaft 41, forming a continuation of which the reduced end 40 gaged by the key 42, the lower end of the shaft 41, Vextending' downward into the casing 10, and passing revolubly through a transverse bar 44, the ends of which are slidably lengaged within slots 45, formed longitudinally in the lower portion of the columns 25, so as to move freely therein.

Secured to the lower side of the bar 44 are brackets 46, Aand rotatably mounted in the brackets is a shaft 48, its ends extending within the slots 45 so as to be guided by the same.

Rigidly mounted upon the shaft 48 is a cylindrical brush 50, the same being contained between the brackets 46, while beyond one of the brackets is a. miter gear 5l meshing with another miter gear 52, fixed jupon the lower end of the shaft 41.

rotated, rotary the telescopic 50, causing it i cally the curved plate 18, from which `they canbe 1 removed by opening the cover 21 in an obvious manner.

I-Iaving thus described my invention what I claim as new and 'desire to secure by Let-` ters Patent, is i 1. In a floor cleaner, the combination with a casing, and a pair of columns arising therefrom, of a shaft journaled horizontally in said columns, means for rotating said shaft, a vertical shaft formed in sections, the lower section being telescopically engaged in the upper sections, gearing connecting between said horizontal andverti-n cal shafts, a transverse bar movable vertiwithin recesses in said columns, brackets extending below said bar, a shaft mounted in said brackets, a rotary brush affixed upon said shaft, and gear connections between said shaft and the lowermostsection of said vertical shaft whereby rotary motion may be communicated to said brush, and means for raising and lowering said signature. r

bar and brush with respect to the surface over which the apparatus moves.

2. In a floor cleaning` machine, the comf 355 bination with a casing, pairs of rollers in 1 the front and rear thereof, and a brush rotatably mounted therein, of a compartment for vreceiving dust in said casing, a plate covering the entrance to said compartment, a `pair `49 of columns rising from the sides of "said casing, cross bars engaging between said columns, a shaft journaled in said columns,

a vertical shaft formedv of telescopic sections,

alinement'ewith thefirst named rod, a turn`- 55 buckleengagingthe threaded ,ends of said rods, whereby said brush may .be raised or lowered, and means' for rotating the' rst named shaft whereby rotary motion may be communicated to said brush. r
